Abstract

PURPOSE:To instantaneously use a propelling pencil by projecting lead by once or twice knocking by providing a lead one-skid O-ring or a spring mechanism performing the same operation as said O-ring to the metal core of the propelling pencil. CONSTITUTION:A lead non-skid O-ring 11 or a lead non-skid open spring 12 or a lead non-skid spring 13 is provided to the leading end part of a metal core or in the vicinity thereof. In this structure, a knocking bar 5 is detached to insert suitable lead 2 in a core pipe 6 and again mounted to be knocked. Whereupon, the lead 2 is moved to the lead non-skid O-ring 11 or lead non-skid open spring 12 or lead non-skid spring 13 by the operations of a chuck 8, a chuck ring 9 and a return spring 10 to stop to become a usable state.

Description
